How do I work this problem? 100 calories to kilocalories

On can determine the percentage of iron in an iron -oxalate complex such as (Kw[Fe(C2O4)y. zH2O) through the method of volumetric analysis in oxidation reduction titration and also spectrophotometry. The whole experiment has been divided into three subparts such that the first part involves the preparation of the iron(III) oxalate complex . In the second part of the experiment , oxalate content of the complex was determined and in the third part of the experiment we will determine the iron content.

Since we need to define the method by which we can determine the Fe content in the given complex therefore we will deal mainly with the first and third part of the experiment.Firstly a crucible is set up by drying in the oven and then it is cooled in a desiccator. After that about 1.2035 g of&nbsp; ferrous ammonium sulphate crystals were taken in a beaker and then they were dissolved in about 50 mL of water. Then about 6mL of 1M oxalic acid was measured using a graduated cylinder and then added to the above complex which leads to the formation of a yellow color precipitate of iron oxalate . The pH of the solution is checked and it should be strongly acidic so that further steps can be followed. This solution is then heated by adding boiling stones until the precipitate is completely dissolved. The solution is then cooled in order to settle down the precipitate. After the precipitate has been dissolved it is then washed about three to four times with DI water in order to clean it properly.

Now about 3mL of 2M KMnO4 is added to this solution in a dropwise manner which will yield an orange colored precipitate. Then this solution is warmed and about 10mL of 6% hydrogen peroxide is added to this solution which will result in a brownish precipitate. The solution is again heated upto its boiling point and then 2mL +15 drops of 1M oxalic acid is added again . Some crystals settle down in the beak...
